Answer:
542.5 km
Explanation:
average thickness of granitic continental crust = 35 km
Average density of crust ( from section C1 ) (pc) = 3.3 g/cm^3
Average density of mantle (Pd) = 3.1 g/cm^3
applying the concept of Isostay
attached below is the missing part of the question and solution
Answer:
D. Seafloor bedrock is younger near the ridge and older farther away.
Explanation:
In a divergence boundary oceanic plates or continental plates move apart. The plates moves apart causing an uprising of molten magma to form a new crust. The divergent movement of plate is very prevalent in the oceanic plates.
The plates in the oceanic crust moves apart due to the up welling of aesthenosphere materials . These aesthenosphere materials(molten magma) are introduce to the ocean floor through the mid oceanic ridge . As this materials are introduced through cracks and fissures, the plates continue to drift apart. The molten magma later solidified to form a new crust closer to the oceanic ridge. This is why sea floor bedrock closer to the ridge is younger as new rocks are formed here. But as one move farther away from the ridge the rocks become older. This phenomenon provide ample evidence that the seafloor is spreading. The older rocks found father away from the ridge proves the seafloor has been spreading given way for new rocks closer to the ridge.
Answer:
Yes, that is very much true, just because climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount of heat radiated back into space by the Earth.
<em>"The change in stability of the environmental factors or the negative effects in the equilibrium inside the environment is called as the climate change."</em>
- <u>Global Warming And the green house effect:</u>
<em>"The overall rise in temperature of the earth spheres and its environment is termed as global warming, and its due the green house effect(the negative effect due to the increase level of CFC's)."</em>
- <u>The trapped Sun radiation inside the earth's sphere:</u>
<em>"Due to large number of CFC's inside the earths sphere, as they results in trapping the radiation which needs to be radiated back out of the earth's sphere. Causing the rise in temperature of the overall environment."</em>
Explanation:
- The chloro, floro and carbon elements which are also termed as the CFC's in general are created due increase level of industrial waste presence in the environment, leading to more solar radiation trapped inside the outer sphere of the earth's protective shield. Due, to this process the gasses are trapped inside the earth's sphere resulting in the rise in temperature.
- <u>Consequences of Climate Change:</u>
- As our earth passed from various levels and situations and as there were also some ice ages, which almost resulted in creating inhabitable situations for the living beings.
- But, these days earth is facing some alarming situations in the form of high temperature in its environment, which is some how leading to some thing more worse.
- There will be less resources of food in the near future and most importantly there will be species like polar bears and some marine animals who will face extinction due to the rise in temperature inside the environment.
Blame culture. I am not a big fan of blaming people when things go wrong.
Blameless culture. In a blameless culture people are free of blame, fear and recriminations and can learn from their mistakes.
are social organization, customs, religion, language, government, economy, and arts.
